Tool Bit Diamond Particle Size When Selecting Diamond Saw Blade

Posted on by

When buying diamond saw blade, please not to neglect the tool bit concentration even if it is not the most important parameters such as cutting linear velocity and cutting depth because it is also related to saw blade’s cutting quality and working life.

OK, at first, I will tell you the definition of diamond concentration, it is the diamond density that distributed in the saw blade working layer, in other words, it is the diamond weight in the unit area. According to related provision, about every cubic centimeter in working carcass, if there is 4.4 carat diamond, it means that the diamond concentration is 100 percent, if there is only 3.3 carat diamond, the diamond concentration is reduced to 75 percent.

Do You Know These CBN Grinding Tools Knowledge

Posted on by

As you know, there are some difference between CBN raw materials and the diamond raw materials, therefore they can be used to cut different materials, take the CBN grinding tools for example, it is suitable for cutting the tool steel, bearing steel, alloy steel, super alloys, cast iron. As for the diamond grinding tools, they can be used to process some hard or crisp raw materials such as cemented carbide, hard stones, glass, ceramics, metal ceramics, concrete and so on. In fact, both of these two grinding tools are complementary, as a result, its using range would be more and more large. If there is high grinding requirement such as precise grinding, such CBN grinding tools are highly recommended to you.

Not To Ignore Two Factors When Selecting Diamond Saw Blade

Posted on by

In the following article, I will mainly talk about the diamond saw blade tool bit binding agent hardness and the power effects, temperature effects when selecting diamond saw blade.

Tool bit binding agent hardness
Generally speaking, the higher hardness of tool bit binding agent, the stronger performance of wear resistance, therefore when using diamond saw blade to cut stone with high hardness, the binding agent hardness should be higher correspondingly, at the same time, when using it to cut soft stone, the binding agent hardness should be lower. When the cutting stone materials is hard, along with strong abrasiveness, the binding agent hardness should be medium.

Pay Attention On Diamond Concentration

Posted on by

As you know, diamond circular saw blades are now widely used for cutting some hard raw materials such as stone, concrete and so on. However, do you know how to choose top quality diamond saw blades for cutting?

Pay attention on the diamond concentration distributed in the saw blades. Generally speaking, in a certain range, the diamond concentration would be changed from low degree to high degree, at the time, the saw blades’ sharpness and cutting efficiency would also be changed to low degree gradually, as a result, its working life would be more and more longer. However, if diamond circular saw blades have too much higher diamond concentration, saw blade would become more blunt, on the contrary, with low diamond concentration and thick particle size, saw blade cutting efficiency would be too much higher.

Nowadays, TCT circular saw blade, which is also known as cemented carbide saw blade, is widely used in industry cutting. For example, it is likely to be used to cut wood, panel, aluminium product, plastics and organic glass. When looking at the appearance of TCT saw blade, you would notice that it is the round and thin steel plate with too many teeth on its edge.

Follow Six Tips To Use Diamond Grinding Wheel Rightly

Posted on by

Have you used diamond grinding wheel for cutting? And do you know which matters needing attention when using it? Believe it or not, it is important to know how to use it with right ways because it is not only related to the cutting quality, but also related to people’s security when using it. A few tips about diamond grinding wheel using are introduced to you at here.

Firstly, before using diamond grinding wheel, you have to install it and at this time you’d better read the products instruction book carefully, on which there would be installation steps and tips. For example, there would be such instruction that checking grinding wheel carefully and make sure that it is not be out of shape and there is no crack and edge breakage on grinding wheel body.

Some Tips About Diamond Circular Saw Blade Using

Posted on by

Before using diamond saw blade for cutting, you should at first install it on saw machine rightly, under such circumstance, you’d better consider the ring flange size, generally speaking, the ring flange diameter should be different according to different saw blade diameter, which should not be too smaller or too bigger. If ring flange size is too much lager, there would be heavy loading on saw machine principal axis, and saw blade bounce condition would be increased, on the contrary, if ring flange is too much smaller, there would be heavier deflection on saw blade when using.

Learn These Knowledge Before Knowing Diamond Saw Blade

Posted on by

Diamond saw blade is one kind of common cutting tools and right now it is widely used in cutting some hard raw materials or crisp raw materials such as stones and ceramics. Similar with other saw blades such as TCT circular saw blade, diamond saw blade is constituted with two parts including its tool bits and matrix.

Tool bits and matrix play different roles in diamond saw blade, generally speaking, matrix plays the role of supporting and bonding tool bit while tool bit plays the role of cutting when using. Because of such different roles, tool bit would be abraded after a long time using while there is no almost any change on the matrix.
